SPINNING-SPINDLE.

SPECIFICATION forming part of Letters Patent No. 732,179, dated June 30, 1903.

Application led September 25, 1902. Serial No. 124,720. (No model.)

To @ZZ whom, t may concern:

Be it known that I, RICHARD FAIR, a citizen of the United States, and a resident of Moosup, county of Windham, State of Con- 5 necticut, have invented an Improvement inV Spinning-Spindles, of which the following deseription, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts. xo This invention relates more especially to the oil snout or nozzle of a spinning-spindle, mounted on the supporting-case of the spindle and adapted to store a supply of oil and direct it to the interior of lthe case and the bolster or other spindle-bearing.

ln oiling spindles operatives are apt to be careless, and often the oil runs over the top of the snout and down onto the rail and adjacent parts and sooner or later comes in con- 2o tact with the yarn.

One of the objects of my present invention is to prevent such slopping over of the oil,

and to this end I have provided an automatic closure for the inlet-opening of the oil-snout, the insertion of the nozzle of an oil-can acting upon the closure to permit the passage of oil through the inlet-opening into the snout,while upon withdrawal of the can-nozzle the closure automatically shuts the inlet-opening.

The various novel features of my invention will be hereinafter described in the subjoined specification and particularly pointed out in the following claims.

One practical embodiment of my invention is herein illustrated and described in connection with a well-known form of spindle-bearing.

Figure l is a View in elevation of a spinning-spindle of the sleeve-whirl type and its.

supporting-case with one embodiment of my invention applied thereto. Fig. 2 is a detail in elevation of the supporting-case and oilsnout viewing the structure shown in Fig. 1 from the right. Fig. 3 is a detail similar to Y Fig. l, but showing the oil-snout and the novel features of my invent-ion in vertical section; and Fig. I is a detail in elevation showing the upper end of the oil-snout, the

closure, and the head of the snout detached 5o therefrom.

In Figs. l, 2, and 3 the supporting-case A, having an enlarged base AX resting upon the spindle-rail M, the spindle S, having a sleevewhirl W, and the retaining-nut 0.x for the supporting-case may be and are all substan- 5 5 tially of well-known construction and operate in usual manner.

As herein shown, the oil reservoir and snout comprises a radially-extended portion d on the base AX, having an upright or upturned 6o tubular portion d, and, as illustrated in Fig.

3, the portion cZ/ has a substantially vertical inletf', communicating at its lower end with the ductfin the part d, the latter communieating with the interior of the casein usual manner.

In order to provide an effective and automatically-operating closure for the inlet f', I herein have shown a head 71. for the snout annularly enlarged and provided with a de- 7o pending tubular neck h to slip over the upper end of the upturned portion dof the oilsnout, the head having a flaring or cup-like entrance hX to an inlet-opening h2 in its bottom,- said opening being of less diameter than the inlet f". (See Fig. 3.) A closure or valve o, having a depending stem o, is located Within the snout portion d and is supported by a spiral spring SX in the present embodiment of my invention, the stem fu entering 8o the upper end of the spring, the lower end of the latter resting on the bottom of the duct f. This closure@` is held by the spring against the under side of the head h, tightly closing the inlet-opening h2, the closure being somewhat larger in diameter than said opening, as shown in Fig. 3. To connect or lock the head to the snout, I have shown the neck h as provided with an l-shaped slot h3, Figs. 2 and 4, which is entered by a radial lug or 9o pin (ZX on the snout portion d', so that after placing the head on such portion and depressing it to bring the horizontal part of the slot h3 opposite the lug cZX a partial rotation of the head will lock it in place. This is a wellknown form of so-called bayonet-joint. I have shown a notch 5 at the inner end of the slot h3 on its lower edge, Fig. l, to receive the lug (1X, and the latter is held in the notch by the upward pressure 10o of the springsx, thereby preventing any accidental release of the head due to jar or vibration of the parts.A The head is made effective to prevent improper lifting of the Whirl W, and to this end the head has secured to it a radial pin h5, Figs. 1 and 3, which projects over the whirl when the head is locked on the oil-snout, forming a downhold for the whirl. The flaring or cup-like portion hX of the head forms an oil-guard, preventing the oil from slopping over when the snout is being filled, and at such time the nozzle of the oil-can must be pushed against the closure o to depress it and open communication between the inlet f and the opening h2 of the head before oil can pass to the snout. By withdrawing the can-nozzle the spring SX instantly operates to press the closure e against the opening h2, tightly and eectually closing it, so that no oil can pass out from the snout. Dust, dirt, lint, &c., are prevented by the closure from entering the snout and mingling with the oil therein.

Having fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

l. In a spinning-spindle, a supporting-case provided with an upturned oil-snout, an enlarged, removable head therefor' to form a cup-like guard around the end of the oilsnout, said head having'an inlet-opening in its bottom, to communicate With the snout, a bayonet-joint connection between the head and the'snout, and a spring-controlled closure .within the snout, to normally coperate with and close the inlet-opening in the bottom of the head, and also to prevent accidental release of the bayonet-joint connection.

2. In a spinning-spindle, a supporting-case provided with an npturned oil-snout, a euplike, removable head therefor having an inlet-opening to commu nicate with the oil-snout and provided with a downhold for the sleevewhirl, a locking device to connect the head and the snout, and a spring-control1ed closure located Within the latter, to engage the inner end of the inlet-opening and prevent communication between the snout and the cup-like head.

3. In a spinning-spindle, a supporting-case provided with an uptnrned oil-snout, a cuplike, removable head therefor having an inlet-opening to communicate with the voil-snout and provided with a downhold vfor the sleevewhirl, a bayonet-joint connection between the head and the snout, a closure located within the latter, to close the inlet-opening, and a spring to maintain the closure seated in operative position and to prevent vaccidental release of the head.

4. In a spinning-spindle, a supporting-case provided with a snout, a detachable head mounted thereon, having an-inlet-opening to communicate with the snout and provided with a downhold for the spindle-whirl, means to lock the head on the snout with the downhold in operative position, and a yieldinglysupported closure for the inne:` end of the inlet-opening, said closure yielding to externally-applied pressure to permit communication between the inlet-opening and the snout.

In testimony' whereot I have signed my name to this specification in the presence of two subscribing Witnesses.

RICHARD FAIR.
